Question

1. Define pH. What does pH measure?

2. Write the definition of an acid. Give two examples of an acid. Organic acids tend to contain what group of elements? (See lecture notes.)

3. Write the definition of a base. Give two examples of a base. Some organic bases contain what group of elements? (See lecture notes.)

4. Compare a hydrogen ion and a hydrogen atom. (Hint: see your chapter 2 worksheet). What atomic particles (and how many) are present in a hydrogen ion? What atomic particles (and how many) are present in a hydrogen atom?

Answer 1

In biochemistry, ph is a scale utilized to establish exactly how acidic or even fundamental a water based answer is. Sour remedies have a reduced ph, while fundamental remedies have a better ph,
The ph of a fix is a degree of the molar awareness of hydrogen ions in the answer and thus is a way of measuring the acidity or maybe basicity of the answer.
An acid is a particle or maybe ion able to donating a proton, alternatively, or, able to developing a covalent connect with an electron pair. Instances of acids are the inorganic materials referred to as mineral acids - sulfuric, nitric, hydrochloric, along with phosphoric acids - and also the natural elements belonging to the carboxylic acid, sulfonic acid, as well phenol organizations.
Natural acids are organic compounds which possess acidic qualities. Given that these acids are natural, a carbon atom should exist in its structure,so team fourteen.
bases are things which, for aqueous remedy, release hydroxide (OH') ions, are slippery to the touch, could taste sour in case an alkali,[1] replace the color of indications (e.g., turn reddish litmus paper blue), behave with acids to create salts, market specific chemical reactions (base catalysis), recognize protons from any proton donor or even have partially or completely displaceable OH' ions. Instances of bases would be the hydroxides of the alkali metals as well as the basic planet metals (NaOH, Ca(OH)2, etc. - see alkali hydroxide as well as basic planet hydroxide.
An organic and natural foundation is an organic compound that functions as being a starting. Natural bases are generally, although not generally, proton acceptors. They typically contain nitrogen atoms,so group fifteen elements
The primary key distinction between hydrogen atom as well as hydrogen ion would be that the hydrogen atom is basic whereas the hydrogen ion has a charge.
Hydrogen forms the sole cation which has absolutely no electrons, but perhaps cations which (unlike hydrogen) still remember 1 or maybe more electrons continue to be lesser compared to the basic atoms or maybe molecules from what they're derived.
The electrically basic atom has one favorably charged proton plus just one negatively charged electron certain to the nucleus by the Coulomb force. 3 atomic particles are there in a single atom.
